James Yeager, the CEO of Tactical Response who recently said “I’m gonna start killing people” if President Obama takes executive action on gun violence, advertises his services as a firearms instructor with a long list of state and federal certifications. One of the more prominent claims is innacurate, according to Tennessee law enforcement.

But Dalya Qualls, a spokesperson for the Department of Safety and Homeland Security, told TPM that’s just not the case.

“I have confirmed with our Handgun Unit that Mr. Yeager is not a Department of Safety and Homeland Security certified handgun instructor and Tactical Response is not a department certified school,” Qualls said in an email.

Though Yeager lists himself as a “firearms instructor,” Qualls told TPM he is not certified by the department and that there is no such certification offered.

A Tactical Response employee who picked up the phone at the company’s Camden, Tenn. headquarters told TPM the company was not responding to questions about Yeager and hung up after being pressed on the certifications.

Here’s a screengrab of the relevant portion the long list of certifications on Yeager’s website:
